Media Streaming Performance in a Portable Wireless Classroom Network

Overview This paper presents empirical measurements of wireless media streaming traffic in an IEEE 802.11b wireless ad hoc network. The results show that the IEEE 802.11b WLAN can support up to 8 clients with good media streaming quality, with each client receiving a separate 400 kbps video stream and 128 kbps audio stream. With 9 clients, the WLAN is overloaded, and performance degrades for all clients. Finally, the paper demonstrates a "Bad apple" phenomenon in wireless ad hoc networks, wherein a single client with poor wireless connectivity disrupts the media streaming quality for all clients sharing the WLAN.
